ABS vs. No ABS - Episode 4
Basically a re-make of Episode 1, with real life footage. A lot of people claim that since past episodes are 3D representations, therefore are fake or innacurate. I know the difference would be much different if surface was wet, oily, with gravel, mud, etc... My videos are based on day to day conditions. Also I´m just trying to make a single point : "It is possible to stop on a shorter distance without ABS" I know it lets you steer, and all that stuff, but right now I´m not dealing with it (maybe later). ABS is a safety feature but it always comes to the driver to manouver correctly under dangerous circumnstances and take the right decitions to avoid an accident. (like lowering your speed if road is on low traction conditions, or not speeding while getting to a blind intersection, etc...) Here´s me demonstrating what I´ve shown in previous episodes. I´m the driver. Notes: - In 2nd Threshold braking, I missed my braking point (a bush I used as reference) so I had to brake a bit harder, you can see ABS is disabled because on the last second my rear wheel locks. - I changed locations because the tests where on different days, I have to find a nice lone road to do them, and the tests of threshold braking I made on the 1st location lacked a lot of references and was very hard to brake always at the same speed, also I had less road to speed up and keep that speed before braking. - I lose speedometer when I disable ABS, how do I know I´m reaching the same speed? well, I perform an ABS test and look at the tachometer to see how much revolutions at certain gear I need for that particular speed (in this case it was 3500 revs in 2nd gear for 55-60 kmph) - The voice is all weird because its from a text to speech engine, it is not me talking. I wanted to narrate stuff instead of typing everything like on past episodes. The car is a standard production car. Opel Astra with stock brakes, braking pads are not new (in fact they need to be replaced) Wheels are Michelin hydroedge, which are great to avoid hydroplaning and they´re very hard, so they last a long way. There´s no flat stop after the full lock test.





ABS vs. No ABS
My personal opinion based on several experiences. I drove for 6 years a car without ABS and had a lot of experiences in it. After another car crashed head on with me and totaled my car, now I drive an ABS equiped car, I´ve been driving it for more than a year, and had also lots of experiences.
